Wheel caster

Abstract

A wheel caster comprising a roller, and a two piece socket, wherein the two piece socket comprises a top housing, having a concave cavity to accept the roller in a freely rotatable configuration, a stem, to be inserted inside a leg of an object, and a bottom housing comprising an opening to allow a portion of the roller to extend below the bottom housing allowing the roller to contact a surface.

What is claimed is: 
     
         1 . A wheel caster comprising:
 a roller; and   a socket comprising:
 a top housing, having a concave cavity to accept the roller in a freely rotatable configuration, the top housing further comprising a stem to be attached to a leg of an object; and 
 a bottom housing detachably attached to the top housing to secure the roller, the bottom housing further comprising an opening to allow a portion of the roller to extend through and below the bottom housing allowing the roller to contact a surface. 
   
     
     
         2 . The wheel caster of  claim 1 , wherein the top housing further comprises a plurality of top connection sockets protruding horizontally outwards from a base of the top housing. 
     
     
         3 . The wheel caster of  claim 1 , wherein the bottom housing further comprises a plurality of bottom connection sockets, to accept a plurality of fasteners to attach the bottom housing with the top housing. 
     
     
         4 . The wheel caster of  claim 1 , wherein the stem further comprises a notch to accept an O-ring around the circumference of the stem to secure the wheel caster to an object. 
     
     
         5 . The wheel caster of  claim 1 , wherein the roller is made up of a material selected from a group comprising one of, a stainless steel, a Teflon, a ceramic, or a combination thereof. 
     
     
         6 . The wheel caster of  claim 1 , wherein the roller comprises a plurality of semi-spherical balls connected to one another. 
     
     
         7 . The wheel caster of  claim 1 , wherein the top housing further comprises a support attached to a distal end of the stem to restrict movement of the leg of the object. 
     
     
         8 . The wheel caster of  claim 1 , wherein the bottom housing further comprises a ring and a support lip such that a diameter of the support lip is smaller than a diameter of the ring. 
     
     
         9 . The wheel caster of  claim 1 , wherein the top housing further comprises plurality of support arms. 
     
     
         10 . The wheel caster of  claim 1 , wherein the top housing further comprises a Teflon insert to reduce friction between the roller and the top housing. 
     
     
         11 . A wheel caster comprising:
 a roller, having a plurality of semi-spherical balls connected to one another; and   a two piece socket comprising:
 a top housing, having a concave cavity to accept the roller in a freely rotatable configuration, wherein the top housing comprises:
 a stem, to be inserted inside a leg of an object; 
 an O-ring wrapped around a circumference of the stem; and 
 a plurality of top connection sockets protruding horizontally outwards from a base of the top housing; and 
 
 a bottom housing, having a plurality of bottom connection sockets, to accept a plurality of fasteners to attach the bottom housing with the top housing when each of the bottom connection sockets are aligned with each of the top connection sockets. 
   
     
     
         12 . The wheel caster of  claim 11 , wherein the top housing further comprises a support attached to a distal end of the stem to restrict a movement of the leg of the object. 
     
     
         13 . The wheel caster of  claim 11 , wherein the top housing further comprises a plurality of support arms. 
     
     
         14 . The wheel caster of  claim 11 , wherein the bottom housing further comprises a ring and a support lip such that a diameter of the support lip is smaller than a diameter of the ring. 
     
     
         15 . The wheel caster of  claim 11 , wherein the top housing further comprises a Teflon insert to reduce friction between the roller and the top housing. 
     
     
         16 . The wheel caster of  claim 11 , wherein the bottom housing further comprises a wiper detachably attached along a circumference of the bottom housing. 
     
     
         17 . A wheel caster comprising:
 a roller;   a top housing, having a concave cavity to accept the roller in a freely rotatable configuration, the top housing further comprising a stem having a plurality of support arms, an O-ring wrapped around a circumference of the stem and a plurality of top connection sockets; and   a bottom housing, having an opening to allow a portion of the roller to extend through and below the bottom housing to allow the roller to contact a surface, and a plurality of bottom connection sockets, to accept a plurality of fasteners to attach the bottom housing with the top housing when each of the bottom connection sockets are aligned with each of the top connection sockets.   
     
     
         18 . The wheel caster of  claim 17 , wherein the top housing further comprises a Teflon insert to reduce friction between the roller and the top housing. 
     
     
         19 . The wheel caster of  claim 17 , wherein the top housing further comprises a support attached to a distal end of the stem to restrict a movement of the leg of the object. 
     
     
         20 . The wheel caster of  claim 19 , wherein the support is attached to the plurality of support arms.
